Show 1 slide 3 Slide 1 Slide 2 Slide 3		Similar to salmon, baby steelhead fish are called fry when they reach around one inch in length. In another 6 weeks, they grow to a size of two to eight inches in length. At that point, they have become juveniles or fingerlings. The hatchery provides a fresh water home for these developing fish for up to thirteen months. To help identify steelhead fish raised at the Hatchery, the adipose fin is clipped. When released these steelhead eventually migrate from fresh water back to salt water. New born fish are called Fry. When they grow to weigh at least one ounce, they are called fingerlings.
